everyone has their boundaries. he made clear he doesn't wanna talk about it, so there's that. it does seem rather suspicious tho, as snapchat is known for... being snapchat. why don't you set up your own account? talk to strangers/friends. if he comes complaining, you got a card up your sleeve. if he doesn't... well, you'll know what snapchat is all about (and might meet new people as a plus).
